How to Unclog a Water Heater: Clear it like a Pro
Everyone relies on their water heater daily, from hot showers to cooking. A clogged water heater can, therefore, be more than a small inconvenience. Follow these steps to clear your water heater like a pro, ensuring you have consistent and efficient hot water supply.
Step 1: Turn Off Power & Water Supply
Before doing any work, ensure safety by turning off the power to the water heater. If it’s electric, switch off the breaker. If it’s gas, turn off the gas supply. Then, shut off the water supply to the heater.
Step 2: Attach a Hose
Attach a garden hose to the drain valve at the bottom of the tank. Run the other end of the hose to an area that won’t be affected by the sediment-filled water, such as a driveway or a gutter.
Step 3: Drain the Tank
Open the drain valve and allow the water to flow out. Once it has drained completely, briefly turn the water supply back on to stir up any remaining sediment, then let it drain again.
Step 4: Flush the Tank
After draining the tank, open the water supply valve to flush out any remaining sediment. Keep the valve open until the water runs clear from the hose, then close the drain valve.
Step 5: Refill & Restore Power
Once the tank is clear, close the drain valve and remove the hose. Refill the tank by opening the water supply valve. After the tank has filled, restore power or turn on the gas supply and relight the pilot, following the manufacturer’s instructions.
- Safety First: Never work on a hot tank. Allow it to cool or use caution when draining hot water.
- Regular Maintenance: Periodically draining your water heater can prevent sediment build-up.
- Inspection: Regularly inspect your water heater for signs of leaks, rust, or other issues.
